Ale-8-One[0] sold their feature soda/pop/coke/soft drink in some areas in returnable bottles at least as late as 2010. Word was that if their bottle washing and sanitizing machine died, they'd have to stop that. It turns out nobody's making parts for those machines any more.
I know they were still accepting returns back in 2020 (I was looking forwards buying some on a road trip and returning it as we came back through KY), but their new website redesign doesn't seem to mention it anymore.
EDIT: The bottles for sale on the website are specifically "non-returnable", not sure if that implies no more returns, or only store-purchased bottles are returnable.
